  <div>
   <p>当存储设备为OceanStor Dorado 6.1.3及以上版本或者OceanStor 6.1.3及以上版本时，可以通过生产存储与<span>本产品</span>之间的复制功能，实现NAS文件系统备份。此时需要分别在存储设备侧和<span>本产品</span>侧，创建复制网络逻辑端口，用于远程复制数据传输。当存储设备为其他类型时，通过NAS共享实现备份，无需创建复制网络逻辑端口，请跳过本章节。</p>
   <div class="section">
    <h4 class="sectiontitle">前提条件</h4>
    <ul>
     <li>已规划主从端复制网络IP地址，复制网络IP地址应与备份网络在同一网段。</li>
     <li>已在本产品的DeviceManager界面中创建“角色”为“管理+数据”、“数据协议”为“NFS + CIFS”的逻辑端口，具体操作可参考<span>《安装指南》</span>中的<span class="parmvalue">“如何创建逻辑端口”</span>章节。</li>
    </ul>
   </div>
   <div class="section">
    <h4 class="sectiontitle">操作步骤</h4>
    <p>下文以在<span>本产品</span>创建复制网络逻辑端口为例。存储设备侧创建方法与此相同。</p>
